About This Conference

The aim of this conference is to bring together scientists from diverse disciplines, who are working on nonstoichiometric compounds such as oxides, nitrides, hydrides, chalcogenides, and mixed-anion compounds. Traditionally, the effects of stoichiometry deviations – nonstoichiometry – have been studied by those looking to understand and control the physical properties of oxides such as transport and mechanical properties, with the aim of using such materials as solid oxide fuel cell electrodes, as sensors, as permeation membranes, and in various other electrochemical reactors.

Complex oxides that exhibit nonstoichiometric effects are now also employed in all-solid-state secondary batteries, thermochemical water splitting and chemical looping systems, as well as in transparent conducting electrodes in displays and photovoltaics. These and other oxides are also being developed for all-oxide electronics, high-speed photonics, switching and memory devices, and magnetoresistive devices. Furthermore, driven by the semiconductor industry, interest has also expanded to include nitrides, chalcogenides, and complex-ion compounds such as MAPbI3.

Given the diverse fields of applications, it is clear that this ECI conference devoted specifically to compounds that display nonstoichiometry will allow scientists from these various fields to learn from the other fields and from other approaches, to assess the state of the art, and to discuss future developments. This conference will thus cover all aspects of nonstoichiometry in inorganic compounds. Topics will include theory, defect chemistry, electrical properties, thermopower, diffusion, electrochemical properties, mechanical properties and solid state reactions, all of which depend on nonstoichiometry. Materials will include single crystalline, polycrystalline and nanocrystalline ceramics with possible applications as mentioned above.

Conference Venue

Kyushu is the third largest island in Japan and the most southwesterly 19AB kyushuof the four main islands.  The island is mountainous, and Japan’s most active volcano, Mount Aso, is on Kyushu.  Parts of Kyushu have a subtropical climate, particularly Miyazaki prefecture.  The island is noted for various types of porcelain.

Miyazaki is located in a southeastern part of Kyushu. Due to its mild weather (an average temperature of 17°C, 2103 hours of daylight a year), phoenix trees and palm trees can be seen everywhere, which gives the city the atmosphere of a bright southern resort. The eastern part of Miyazaki prefecture faces the Pacific Ocean throughout the region; the sun ascends from the Pacific Ocean. The moonlight is also very beautiful. Therefore, it is called “the sunny place Hyuga”.

A special place to see in the city is the Miyazaki Shrine, 19AB Miyazaki Shrinebuilt deep in the woods, with a Torii gate (shrine gate) made from simple, plain wood. It is a very unique shrine as it is built only with cedar. Miyazaki is also known as a mythological country as there are many sightseeing places relating to “Kojiki” (Record of Ancient Matters), which is the oldest existing record of Japanese history and collection of Japanese mythology.

The conference site, Seagaia, is conveniently located 20 minutes from Miyazaki Airport (KMI). There are frequent (15-18 per day) flights from from Haneda (HND) (Also known as Tokyo International Airport) (90 minutes), Osaka Itami (ITM) (60 minutes), and Fukuoka (FUK)(40 minutes).  International flights are available from Seoul, Taipei and Hong Kong.

All rooms are equipped with ocean view.

General Information about ECI

Engineering Conferences International (ECI) is a global engineering conferences program, originally established in 1962, that provides opportunities for the exploration of problems and issues of concern to engineers and scientists from many disciplines.

The format of the weeklong research conference provides morning and late afternoon or evening sessions in which major presentations are made. Available time is included during the afternoons for ad hoc meetings, informal discussions, and/or recreation. This format is designed to enhance rapport among participants and promote dialogue on the development of the meeting. We believe that the conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums.

All participants are expected both to attend the entire conference and to contribute actively to the discussions. The recording/photographing of lectures and presentations is forbidden. As ECI conferences take place in an informal atmosphere, casual clothing is the usual attire.
